Implement file sending via Jingle
This is still disabled by default until prioritization is implemented; otherwise this could be preferred to HTTP uploads. File sending only works via Jingle In-Band-Bytestreams right now, more transports are going to be implemented. To test this, uncomment the line with `JingleFileTransfer` in libdino/src/application.vala.
